Abstract

In this paper, a method is proposed to reduce the write energy consumption in order to reduce the energy consumption of the circuit composed of spin-torque transfer magnetic RAM(STT-MRAM). Of the total energy consumption of the circuit, the write energy consumption occupies a large proportion. Omission of unnecessary write operations increases efficiency in terms of energy consumption. Compare the data to be written with the data to be written before proceeding with the write operation of the circuit to omit the unnecessary write operation and selectively execute the necessary write operation. As the number of MTJ increases, the gain in side of energy can be increased, so the simulation had proceeded by increasing the number of MTJ to 512. Simulation results show that the worst case energy consumption consumes 16.5% more energy than the conventional one, but it can reduce energy consumption by up to 90.6% at best. Reliability also increases through the process of comparing write data (WD) with data stored in MTJ.
